PATTERN-CHAIN FOR LooMs'.

SPECIFICATION forming part of Letters Patent No. 224,550, dated February 17, 1880.

Application filed October 31, 1879. Patented in Germany, January 9, 1879.

i To all whom it may concern:

Be it known that I, MORITZ LINDNER, of GhemnitmKingdom of Saxony, have invented an Improvement in Pattern-Chains for Looms, of which the following is a specification;

Figure l is a face view of a pattern-chain containing my improvement. Fig. 2 is an edge view of one of the tappets thereon; Fig.

'3, a central section thereof; Fig. 4, a central section of the parts thereof separated; Fig. 5, a face View of said tappet. This invention, for which I received a German patent of fifteen years, dated January 9,

1879, No. 6,692, relates to a new construction of the little tappctsor disks used on the pattern-chains of looms., Such pattern'chains (of which one is represented in Fig. 1) require large numbers of small tappets or disks A A, which, being adjusted at the requisite distances apart, furnish projections for moving the threads in the loom in the desired order.

Heretofore these disks or tappets were made of cast-iron, adding materially to the weight of thechain and interfering with its proper easy motion, besides unduly wearing the parts with which they are brought in contact and the supporting-journals of the chain.

My invention seeks to. avoid this undue weight and the disadvantages resulting there from; and it consistsin constructingeach of the disks or tappets A of two pieces of stamped metal of peculiar form-that is to say, I make each roller A of two saucershaped halves, a and b. The rim a of the half a is somewhat larger in diameter than the rim b of the part b, so that when the two parts are put together, by placing the rim b into the rim a as in Fig. 3, they will be and remain firmly united by frictional contact without requiring further fastening. They are likewise properly centered by this connection.

In the center of each saucer-shaped piece a b is a circular opening, 0, and around the same an inwardly -pro jecting'annular ring, f, as shown. These two rings f f-conslitute a bearing-snrface for supporting the tappet at the requisite right angle upon the rod-shaped link of the chain. They also prevent the tappet from tilting on the chain.

I claim- Apattern-ohain composed of bars hingedtogether, as described, each bar being provided with tappet-rolls A, that consist each of two saucer-shaped parts, a b, of different diameters, firmly united by their rims a 6 each part having a central aperture, e, and inwardly-projecting ring f, substantially as herein shown and described.

The foregoing specification of my invention signed by me this 30th day of June, 1879.
